Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a windshield used in a weighing device, and more particularly to a windshield used in a precise weighing device having a relatively small weight.

[0002]

[Prior Art]

 In a weighing device such as an electromagnetic balance type electronic balance that accurately measures a load to be measured, for example, in an electronic balance that displays 0.01 g at a maximum weighing amount of 6 kg, each part of the weighing mechanism is configured to operate even with a minute load. Therefore, the weighing pan on which the weighed material is placed may be agitated by the flow of air, making accurate measurement impossible. In addition, when the measurement target is, for example, a very small amount of powder, there is a possibility that part of the powder may be scattered even with a relatively gentle air flow.

Therefore, a device having a weighing chamber formed so as to cover the weighing object disposing portion around the weighing dish with glass or the like so as to be isolated from the outside has heretofore been partially used. Recently, a windshield formed separately from the scale has also been devised, and a configuration has been proposed in which even if the scale originally does not have a weighing chamber, the windshield covers the portion to be weighed. Conventional examples of these structures include Japanese Utility Model Publication No. 54-19183 and Japanese Utility Model Publication No. 54-37321.

[0004]

[Problems to be solved by the device]

 Among them, Jikkou 54-19183 has a structure in which a folding windshield, which is formed separately from the scale, is attached to the balance. Jikkou 54-37321 is a multipurpose cover for the windshield that can be opened and closed with respect to the weighing device body. It has a built-in configuration. In both the conventional example and the configuration in which the weighing chamber is fixedly formed in advance, the structure for avoiding wind is a structure formed in a part of the weighing device centering on the weighing dish.

In the weighing device having the above configuration, when the air flow is relatively gentle, these wind avoiding structures effectively function and precise weight measurement is possible. However, these wind-preventing structures are not sufficient in the vicinity of the air outlet of the air conditioner, in places where people come and go, or in places where indoor and outdoor air flow is large due to opening and closing of doors. When opening and closing the weighing chamber or the wind shield space defined as a windshield, the flow of external air may disturb the space inside the weighing object placement section, making it impossible to perform accurate measurements.

[0006]

[Means for Solving the Problems]

 The present invention is a windshield configured to solve the above-mentioned problems, and includes a lower cover that forms a plurality of side walls and an upper cover that shields the upper part of the space formed by the side walls of the lower covers. And a transparent portion that allows the internal space to be viewed is formed in at least the upper cover, the entire weighing device is arranged in this space, and the upper and lower covers are configured to be foldable. It is a windshield for a weighing device.

[0007]

[Action]

 The entire weighing device is housed in a windshield constructed by connecting and connecting the upper and lower covers, and the windshield protects the entire weighing device from air flow.

In the above configuration, the front wall portion 5 is provided continuously with the side wall portion 4b). Further, a part of the side wall portions 4a and 4b are oblique portions 4a 'and 4b' which are obliquely cut out toward the tip portion, and the front wall portion 5 is provided at the tip of the oblique portion 4b '. It is attached. Boundary portions of the respective wall portions 3 to 5 are bent portions 6, and the bent portions 6 allow the respective wall portions to be folded. A connecting portion 5a is also continuously provided at one end of the front wall portion 5 via a bent portion 6, and a hook 7 serving as connecting means is provided at the connecting portion 5a.

The lower cover 1 having the above structure is folded as shown in FIG. 1 when it is carried or not used. At the time of assembly, first, the wall portions 3, 4a, 4b and 5 are orthogonal to each other as shown in FIG. Then, the lower cover 1 is formed in a box shape by fastening the hook 7a of the connecting portion 5a and the hook 7b of the side wall portion 4a which are continuously provided to the front wall portion 5.

In FIG. 3, the upper cover 2 is configured to be attached to the lower cover 1 formed in a box shape as described above (see FIG. 3).

The upper cover 2 is formed in a shape that covers the upper open space of the lower cover 1 formed in a box shape. That is, of the upper end edges of both side wall portions 4a and 4b of the lower cover, a substantially rectangular shape is formed so as to cover the horizontal portions 4a "and 4b", the slant portions 4a 'and 4b', and a part of the front wall portion 5. Formed when the upper cover is deployed. Further, in the upper cover 2, bent portions 8a and 8b are respectively formed at the positions where the horizontal portions 4a ″ and 4b ″ and the oblique portions 4a ′ and 4b ′ intersect and the position corresponding to the upper end edge of the front wall portion 5, respectively. Has been formed. Thus, when the upper cover 2 is attached to the lower cover 1, the upper cover 2 comes into close contact with the lower cover 1. Reference numeral 10 denotes a transparent portion formed on the upper cover 2, and the surrounding opaque portion functions as a frame for holding the transparent portion 10.

Reference numerals 9a, 9b, 9c are continuously provided via bent portions 8, 8, 8 at positions corresponding to the horizontal portions 4a ″ and 4b ″ of both side wall portions of the upper cover 2 and the rear wall portion 3. The upper cover 2 is connected to the lower cover 1 by fastening the hook 11 as the connecting means provided on these connecting portions 9a to 9c and the hook 7 on the side of the lower cover 1 to each other. A windshield for the device is formed. Further, the upper cover 2 becomes swingable around the bent portion 8a, and also functions as a door of the windshield for the weighing device.

FIG. 5 is a cross-sectional view of a part of the lower cover 1, showing an example of a configuration state of the lower cover 1 and the upper cover 2. Reference numeral 12 is a core material for maintaining the strength of each wall surface part, and is formed of a material having a specific shape and having a certain strength as itself, such as cardboard or plywood such as a plywood board. Reference numeral 13 is a skin material that covers these core materials 12 and is made of synthetic resin such as vinyl. The bent portion 6 is made of only the skin material 13, and the deforming force of the skin material 13 serves as a hinge when the respective wall portions are opened and closed. It should be noted that the upper cover 2 and the lower cover 1 may be formed of plastics, for example, in addition to this structure, and it does not matter what the structure is. Further, the transparent portion may be formed outside the upper cover 2 and on the wall surface portion of the lower cover 1. Further, in the configuration shown in the drawings, the lower cover 1 has no bottom plate portion, but a bottom plate portion connected to any of the wall portions 3 to 5 may be formed.

FIG. 4 shows an example of use of the windshield for the weighing device shown above. Reference numeral 14 is an electronic balance, which is a weighing device housed in the windshield for the weighing device, and is a weighing device that originally has no windshield. When using this weighing device 14, first, the upper cover 2 is loosely opened in the Y direction. When the weighed product is placed on the weighing pan 14a, the upper cover 2 can be held by one hand and the other hand can be used to place the weighed product or operate the weighing device 14. When the cover 2 is completely opened in the Y direction, the swinging portion of the upper cover 2 is stationary so as to be parallel to the horizontal portions 4a ″ and 4b ″ of the side wall portions 4a and 4b. Therefore, use both hands in this state. It is more reliable to operate by doing. When the placement of the item to be weighed on the weighing device and the keyboard operation are completed, the upper cover 2 is closed in the X direction and the measurement is performed in a sealed state.

Further, the weighing device housed in the windshield for the weighing device is not limited to a device having no windshield as shown by reference numeral 14, but also a device equipped with a windshield covering the weighing pan portion of the weighing device 14, or a weighing device. The chamber 15a may be a preformed weighing device 15. Further, the connection of each part may be simplified by using a surface adhesive such as Velcro (trademark) in addition to the above-mentioned hook. Although the upper cover 2 is separated from the lower cover 1 in the illustrated structure, the entire windshield is integrally formed by, for example, being integrally provided to the rear wall portion 3 via a bent portion. You may do it.

FIG. 6 shows a state in which a weighing device having still another structure is housed. The weighing device 16 includes a weighing device body 16a, a setting / display unit 16c, and an arm 16b connecting the weighing device body 16a and the setting / display unit 16c, and by rotating the arm 16b. The setting / display unit 16c can be used in a position where the arm is erected or in a position 16c 'where the arm 16b is tilted. Since the present windshield is constructed so that the weighing device can be used in any state, and in this case the transparent portion 10 is formed over almost the entire surface of the upper cover 2, the windshield can be set from outside the windshield in any state. The display portion 16c can be viewed well.
